Abstract (en)

[origin: WO2012027063A1] A system and method of cooling a compressed working fluid is disclosed. The method includes compressing the working fluid above its critical pressure point in a compression stage to generate a compressed working fluid at or about local ambient temperature. The compressed working fluid can be cooled to below ambient by throttling a portion of the compressed working fluid to its saturated liquid-vapor state to generate a recycle working fluid. The recycle working fluid may then be atomized using an atomizing nozzle whereby the recycle working fluid evaporates and cools working fluid entering a target compression stage.
